I am currently taking the Action Center course; I have completed the course and answer the survey. In my course curriculum, the status for the survey is completed but the course itself says Resume, I have resumed many times but still the status is resume and the survey is completed. I cannot get my Diploma due to this issue.
Please close all the tabs and restart your system and then try checking the progress and this type of issue arises when you use the course in 2 tabs or else 2 browsers simultaneously.
If still the issue persists please try to complete the course in different browser.
